“…Fletcher et al [4] also used symptom severity to characterize the virulence of M. perniciosa. The severity of disease symptoms is dependent on the isolate, spore inoculum and the host tolerance levels to the pathogen [18]. The white isolates of M. perniciosa showed less pathogenicity compared to the yellow/brown isolates.…”

Wet bubble disease, caused by Mycogone perniciosa, is a major threat to Agaricus bisporus production in China. In order to understand the variability of in genetic, pathogenicity, morphology, and symptom production of the fungus, 18 isolates of the pathogen were collected from diseased A. bisporus in different provinces in China. The isolates were characterized by a combination of morphological, cultural, and molecular pathogenicity testing on different strains of A. bisporus and amplified fragment length polymorphism (AFLP) analysis. The 18 isolates were identified by Koch’s postulate and confirmed different pathogenic variability among them. The yellow to brown isolates were more virulent than the white isolates. AFLP markers clustered the isolates into two distinct groups based on their colony color, with a high level of polymorphism of Jaccard similarities ranges from 0.39% to 0.64%. However, there was no evidence of an association between the genetic diversity and the geographical origin of the isolates. Through knowledge of the genetic diversity, phenotypic virulence of M. perniciosa is a key factor for successful breeding of resistant strains of A. bisporus and developing of an integrated disease management strategy to manage wet bubble disease of A. bisporus.

“…Disease severity was recorded on a 0-5 scale, with 0 representing no infection and 5 denoting complete infection (Table 2). The 0-5 scale of disease severity was classified following Ma et al (2019), Rokni andGoltapeh (2019), andSingh et al (2021).…”

IntroductionMorchella esculenta is a popular edible fungus with high economic and nutritional value. However, the rot disease caused by Lecanicillium aphanocladii, pose a serious threat to the quality and yield of M. esculenta. Biological control is one of the effective ways to control fungal diseases.Methods and resultsIn this study, an effective endophytic B. subtilis A9 for the control of M. esculenta rot disease was screened, and its biocontrol mechanism was studied by transcriptome analysis. In total, 122 strains of endophytic bacteria from M. esculenta, of which the antagonistic effect of Bacillus subtilis A9 on L. aphanocladii G1 reached 72.2% in vitro tests. Biological characteristics and genomic features of B. subtilis A9 were analyzed, and key antibiotic gene clusters were detected. Scanning electron microscope (SEM) observation showed that B. subtilis A9 affected the mycelium and spores of L. aphanocladii G1. In field experiments, the biological control effect of B. subtilis A9 reached to 62.5%. Furthermore, the transcritome profiling provides evidence of B. subtilis A9 bicontrol at the molecular level. A total of 1,246 differentially expressed genes (DEGs) were identified between the treatment and control group. Gene Ontology (GO) enrichment analysis showed that a large number of DEGs were related to antioxidant activity related. Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis showed that the main pathways were Nitrogen metabolism, Pentose Phosphate Pathway (PPP) and Mitogen-Activated Protein Kinases (MAPK) signal pathway. Among them, some important genes such as carbonic anhydrase CA (H6S33_007248), catalase CAT (H6S33_001409), tRNA dihydrouridine synthase DusB (H6S33_001297) and NAD(P)-binding protein NAD(P) BP (H6S33_000823) were found. Furthermore, B. subtilis A9 considerably enhanced the M. esculenta activity of Polyphenol oxidase (POD), Superoxide dismutase (SOD), Phenylal anineammonia lyase (PAL) and Catalase (CAT).ConclusionThis study presents the innovative utilization of B. subtilis A9, for effectively controlling M. esculenta rot disease. This will lay a foundation for biological control in Morchella, which may lead to the improvement of new biocontrol agents for production.

“…Button mushrooms (Agaricus bisporus L.) are susceptible to mechanical damage and microbial infections in case of improper storage (Rokni and Goltapeh 2019). Generally, after 3-4 days of storage at room temperature, the mushroom begins to lose firmness, colour and moisture, leading to a reduced market value.…”

Natural additives obtained from vegetable and fruit wastes can potentially be used as coatings to enhance the shelf life of button mushrooms (Agaricus bisporus). The present study was therefore conducted to assess the effects of natural additive coatings A. bisporus polysaccharides (ABP) and Torreya grandis essential oils (TEO) on the post-harvest quality of button mushrooms up to 16 days under cold storage (4 °C). Different concentrations for coatings were used including control (no additives), 500, 1 000, 5 000 ppm or a combination of ABP and TEO. Changes in weight loss, firmness, polyphenol oxidase (PPO) activity and microbial biomass were investigated as well as the sensory evaluation was carried out. Results show a significant decrease in the weight loss rate (decreased up to 2.34%), down regulated the PPO activities (reduced up to 30.15%) and maintained tissue firmness in ABP/TEO treatments compared to the control, whereas TEO inhibited especially the growth of microorganisms. Natural additive coatings can better protect the inner mushroom colour and flavour compared to the control.
